Lette/rs Patent N a. 93,790, dated February 15, 1870.

The Schedule referred` to in these Letters Patent and making part of the same.

To whom itanay concern Be it known that I, JOHN L. SECOMB, of Detroit, in the county of' Wayne, and State of Michigan, have invent-ed a new and useful Improvement in Spring Bed-Bottoms; and Ildo declare that the following is a true-'and accurate description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, and being a part of this specification, in which-'- Figure l-represents a plan view of my invention, with a. portion broken out to show the central springs.

Figure 2 is an end elevation of the same.

Like parts are indicated by like letters in each iigure.

The nature of this invention relates to an improvement in spring bedbottoms; and

It consists in the employment and arrangement of spring bars at the head and foot, Vand the arrangement ot' said spring bars with the other portions of said bottom, which are known devices, the whole forming aY durable, economical, and very elastic article.

In the accompanying drawings- A represents two longitudinal bars, designed to he of a suitable length to tit between the head and footboards of a common bedstead. A

To these bars A are secured, at or near their ends,4 the transverse bars B, Whose length should correspond to the desired width of the hed, and which, in conjunction with the bars A, form the frame of my bed-bottom.

Other and wider transverse bars, G, are also secured at their ends to the bars A, and form supports for the spiral springs D, which are secured to said bars in any proper manner.

the vertical guide-'rods F, which pass upward through suitable holes in the bars B, and are secured at their upper ends to the transverse bars G. I

The longitudinal slats H are secured near their ends to and upon the transverse bars G by means of staples a, screws, or by otherappropriate devices; and the upperends ofthe series of' spiral springs i) are secured tothe slat-sH.

Gare should be taken that the bars C, with the spiral springs imposed thereon, are placed relativelyY nearer the head of the frame than to the foot thereof',

in order that the springs `maybe brought under the heavier portions of the person in the bed.

lhe spiral springs being depressed by the weight of the occupants of the bed, the spring bars above described will be correspondingly depressed by the weight of the extremities of the persons, and the bed will be found elastic, and readily conforming to the shape of the body.

'What 1 claim as my invention, and desire t'o secure by Letters Patent, is

In combination with' the spring bars E, with the guide-rodsV F, and transverse bars B and G, the frame composed ofthe bars A and B, the bars C, the spiral springs D, and slats H, when constructed as described and arranged to operate as Set forth.
